' SPEED-RECORDER.

Specification of Letters Patent.

Patented Sept. 16,1913.

Application filed Key 7', 1907. Serialliol 372,355,

To a] Z whom it may concern Be it known that I.' O'rro JOHANN America, a citizen of the Confederation of Switzerland, residing at Bern, in the Can'- ton of Bern "and said Confederation, have invented certain new and useful lmprovementsin Speed-Recorders, of which the tollowing is a specification, reference being had to the accompanying drawings,

My invention relates to improvements in speed recorders; and an object of my invention is to provide means for making a record, upon a strip of paper, of the speed and the time of the day, so thatthe speed at any given time may be read from the record. 7

In the drawings illustrating the principle of my invention and the best mode now known to me of applying that principle, Figure 1 is a section on the line AB of Fig. 2; Fig. .2 the casing being broken away; and Fig, 3 shows a strip of paper bearing a recor of speed and time as made by my new speed recorder. illustrating the combined mechanism.

Fastenedupon the case 1 is a housing 2 in which is mounted a clockwork, mechanism'having an hour-shaft 30 and adapted to be wound up by turning the milled head 3. hand 5 and the minute-hand 6 of this-clockwork mechanism. The dial-plate 4 is mounted upon the wall 13 from which project two studs 12, into longitudinally-extending, straight slots 11 :tormed one on each side of the enlarged upper end or head of the actuator-arm 8. The enlarged upper end'or head of the actuator-'arm 8 -is also with longitudinally extending slot, through which the hour-shaft 30 projects, and by which. the necessary freedom of movement of the arm 8, without interfer' ence with said hour-shaft, is insured. Upon the hour-shaft 30 is mounted a heart-shaped cam '7 which is adapted to rub against the camrollers 14 carried by the head of the actuator-arm 8. It willbe obvious that by the rotation of the heart-shaped cam 'Z, the gr actuator-arm will be moved back and forth; The actuator-arm is guided by the walls of the casing 1 and by the the opening 9 in the pins 12, 12'projecting into the slots 11,

is a side elevation part of Fig. 4 is a diagrammatic view,-

Over the dial plate 4 move the hour- "and described in the 11. Mounted free to rotate near the center of the case 1 is a sector having a series of teeth 16 which mesh with the teeth 15 upon the lower end oi? the actuator-arm 8 and another series of teeth 18 which mesh with the teeth 19, formed upon the upper end of the timerecording bar 21, the lower end of which is provided with stylus or marker 20. By means of: the toothed sector 17, the reoiprocating motion of the actuator-arm Sis transmitted to the time-recording bar 21; and the actuatingparts' are so arranged that the movementof: the marker 20 is uniform. In the lower. portioncf the case 1 is mounted a-plate 23 having an opening 22 through 'wliichds exposed a strip of paper%. Upon the-latter is ruled lines. equidistant apart. The movcment of the time-recording bar 21 is suchthat the marker moves across the exposed portion of the strip of paper 2% in QIlGdilfiCtlOIl in six hours and in the opposite direction in the following sixthonrs.

' Hence the distance between the ruled lines on the strip of paper 24 may be taken torepresent. a period of one hour. The strip of paper 24 is moved lengthwise byany suitable apparatus; as, for example, the apparatus described in the Swiss Patent, No.

27,946, granted to Arnold Werthmiillcr.

For example, as shown in Fig. 4:, a drum A is illustrated; that is mounted on a shaft B and A is? continuously driven th-1'om hsuitable geaizing G from any. source oil power. The= movement of the stripof paper 24 is made "uniform by this apparatus and conq e ly theliae r wn y t e marker 0 will-be a straight line, the motion of the time-recording bar alreadyexplained. In Fig. 3 is shown a strip at paper which bears a record of speed and time as made by mynew speed recorder; The irregular line-25 is the s eed line'and is made by bar 10, which may be taken as representing conventionally the speed recording mechanism. The latter may beer the type shown 7 Swiss Patent, No. 27 ,946, above referred cording mechanism is amma'tic manner in illustrated in a dia- Fig. 4E, and follows the'structure disclosed in the said Swiss patent-.- It is deslgnated generally by the reference numeral D, The lowermost of the toirepresent six oclock am. and six oclock to. The speed re 21 being uniform, as

the Jrspeed-recor ing 7 ruledlines on the strip of paper 24 is taken p. and the uppermost line will represent twelve oclock noon and twelve oclock v midnight. The ordinates of the speed-curve from the timethe stop is made.

25 measured from the lowermost line ofthe strip perpendicularly thereto giving the speeds at the times indicated by the hourline26.

"In the particularv case illustrated by the strip shown in Fig. 3, thestart was made at 6:30 ocloclr. Shortly before seven oclock a stop was made and, as will be seen by the length of the straightpart a of the speed curve and the corresponding part of the hour line, the trip was continued after a delay of five minutes Shortiy after seven ocljock another stop was made and as is shown by the straight part b of the speed curve and the corresponding part of the hour line, this stop lasted fifteen minutes.

At 7:30 oclock aym. the automobile was stopped for avthird time and did not start until a quarter pastten oclock a. n1. As is described in Swiss Patent, No. 27,9t6, the speed recording mechanism is always main tained wound up during the running ofthe automobile and after the automobile is brought to a stop the speed recording mechanism runs down within fifteen minutes straight part Z? shows that the speed-recording meehanisinran down but that the clockwork-mechanism continued in motion, making'thisstraight part Z of the hour line 26.

The straight part 0 together with the corresponding portion of the hour line indicates that the stop lastedfrom 7 :30 oclock a. in. to quarter'past 'ten oclock a. m. as has been previously stated. lhe next stop was made at about 10 :30 oclock a. m.'and lasted until five oclock 'p.- m, as isplainly shown by the last'straight part of the speed-curve and the corresponding part of the hour-line 26. The part Z of'the hour-line shows that. the clockwork mechanism continued in opera- The messestion after the speed-recording mechanism had run down.

From the foregoing description in connection with the drawings, it will be seen that my new speed recorder will be of great value in case of a dispute as to the speed maintained by the machine at, any given time,'.as' where the police authorities say that the'speed was .at a given time in excess 7 i I of that allowed by the law.
